Visible light-responsive TiO2 (Vis-TiO2) thin film has been deposited on two different kinds of anodized Ti-metal substrates, i.e., plate-type Titanystar (P-Titanystar) or non-woven fabric Titanystar (N-Titanystar) by a radio-frequency magnetron sputtering (RF-MS) method. These Vis-TiO2 thin film photocatalysts (Vis-TiO2/P-Titanystar and Vis-TiO2/N-Titanystar) showed high activity for the oxidation of 2-propanol in water under UV light irradiation while Vis-TiO2/N-Titanystar showed higher activity than Vis-TiO2/P-Titanystar. Furthermore, photocatalytic activity of Vis-TiO2/N-Titanystar was enhanced by the Pt deposition by an RF-MS deposition method. Pt loaded Vis-TiO2/N-Titanystar (Pt-Vis-TiO2/N-Titanystar) acted as an efficient photocatalyst for the oxidation of methanol vapor under UV light irradiation even in a flow system.

Abstract

Visible light-responsive TiO2 (Vis-TiO2) thin film has been deposited on two different kinds of anodized Ti-metal substrates, i.e., plate-type Titanystar (P-Titanystar) or non-woven fabric Titanystar (N-Titanystar) by a radio-frequency magnetron sputtering (RF-MS) method. These Vis-TiO2 thin film photocatalysts (Vis-TiO2/P-Titanystar and Vis-TiO2/N-Titanystar) showed high activity for the oxidation of 2-propanol in water under UV light irradiation while Vis-TiO2/N-Titanystar showed higher activity than Vis-TiO2/P-Titanystar. Furthermore, photocatalytic activity of Vis-TiO2/N-Titanystar was enhanced by the Pt deposition by an RF-MS deposition method. Pt loaded Vis-TiO2/N-Titanystar (Pt-Vis-TiO2/N-Titanystar) acted as an efficient photocatalyst for the oxidation of methanol vapor under UV light irradiation even in a flow system. Moreover, it was found that Pt-Vis-TiO2/N-Titanystar is an effective photocatalyst for the oxidation of various organic compounds in gas phase or ammonia gas even under visible light irradiation (λ > 420 nm) at 293 K.
